This repo contains Docker images for Vespa development on CentOS 7. vespa-build-centos7 is used for only building Vespa, while vespa-dev-centos7 is used for active development of Vespa with building, unit testing and running of system tests. vespa-dev-centos7 depends on vespa-build-centos7. To pull the images:

docker pull docker.io/vespaengine/vespa-build-centos7:latest
docker pull docker.io/vespaengine/vespa-dev-centos7:latest

Commits to master will automatically trigger new builds and deployment on Docker Hub.

This guide describes how to build, unit test and system test Vespa on CentOS 7 using Docker. When doing Vespa development it is important that the turnaround time between code changes and running unit tests and system tests is short. vespa-dev-centos7 provides a complete environment for this. The code is compiled using mvn, cmake and make and then installed into your personal install directory. Vespa can be executed directly from this directory when for instance running system tests.

Make sure Docker has sufficient resources:

Open Docker - Preferences - Resources and set:

• CPUs to minimum 2. Use 8 or more for faster build times.
• Memory size to minimum 8 GB. 16 GB is preferred.
• Disk image size to 128 GB.

Make sure Docker can be executed without sudo for the scripts in this guide to work:

sudo groupadd docker
sudo usermod -aG docker $(id -un)
sudo systemctl restart docker

Perform a new ssh login to the host.

docker pull docker.io/vespaengine/vespa-dev-centos7:latest

First, create a long lived Docker volume. This lets us persist data generated by and used by the Docker container. Skip this step if the volume already exists.

docker volume create volume-vespa-dev-centos7

Second, create the container by mounting the volume as the home directory inside the container:

docker create \
    -p 127.0.0.1:3334:22 \
    -v volume-vespa-dev-centos7:/home/$(id -un) \
    --privileged \
    --name vespa-dev-centos7 \
    docker.io/vespaengine/vespa-dev-centos7:latest

A directory on the host machine can be mounted into the container using the -v option. This lets us persist data generated by and used by the Docker container. When running Docker on a Linux host there is basically no overhead doing so. First, create a volume directory on the host:

mkdir -p $HOME/volumes/vespa-dev-centos7

Second, run docker create with the -v option to mount the volume directory as the home directory in the container:

docker create \
    -p 127.0.0.1:3334:22 \
    -v $HOME/volumes/vespa-dev-centos7:/home/$(id -un) \
    --privileged \
    --name vespa-dev-centos7 \
    docker.io/vespaengine/vespa-dev-centos7:latest

docker start vespa-dev-centos7

Ensure you have an SSH key before running the configure-container.sh script. If not, use the following guide to generate a new SSH key.

mkdir -p $HOME/git
cd $HOME/git
git clone [email protected]:vespa-engine/docker-image-dev.git
cd $HOME/git/docker-image-dev/dev/centos7
./configure-container.sh vespa-dev-centos7

This adds yourself as user in the container, copies authorized keys to ensure ssh can be used, and sets environment variables needed for building Vespa.

cd $HOME/git/docker-image-dev/dev/centos7
docker build -t vespaengine/vespa-dev-centos7:latest .

Use this for testing if doing changes to the Docker image.

ssh -A 127.0.0.1 -p 3334

mkdir -p $HOME/git
cd $HOME/git
git clone [email protected]:vespa-engine/vespa.git

cd $HOME/git/vespa
./bootstrap.sh java
mvn clean install --threads 1C -DskipJavadoc -DskipTests

cd $HOME/git/vespa
cmake3 .
make -j 9

Set the number of compilation threads (-j argument) to the number of CPU cores + 1.

make install/fast

Default install directory is $HOME/vespa ($VESPA_HOME).

mvn test --threads 1C

mvn test --threads 1C -pl container-search

ctest -j 9

ctest -j 9 -R "^searchlib_"

cd $HOME/git
git clone [email protected]:vespa-engine/system-test.git

Note that the system test scrips are already in your PATH inside the Docker container.

nodeserver.sh

cd $HOME/git/system-test/tests/search/basicsearch
runtest.sh basic_search.rb

XQuartz is a version of the X.Org X Window System for macOS. Download here.

Set AddressFamily inet inside /etc/ssh/sshd_config and restart sshd:

sudo kill -HUP <sshd-pid>

Open a XQuartz terminal and run:

ssh -Y -A 127.0.0.1 -p 3334

Then start CLion or IntelliJ from this terminal.
